JACOB B. LATSCHAVV, OF DURAND, WISCONSIN.

TRACK-RAISER.

SPECIFICATION forming part of Letters Patent No. 362.163, dated May r3, 1887.

Serial No. 228,713. (No model.)

T0 all whom it may concern.-

Be it known that I, JACOB B. LATSCHAW, a citizen of the United States, residing at Durand, in the county of Pepin and State of Wisconsin, have invented certain new and useful Improvements in Track-Baisers; and I dodeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, re1"erence being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to trackraisers operated by means of a jack-screw set vertically in the frame of the machine; and its objects are, first, to enable the machine to be readily taken apart for purposes of transportation or storage, and, second, to adapt it to the raising ot' bridgestringers equally with its primary function. These objectsI attain by mounting the jackscrew in a frame-work whose parts are made detachable from and attaehable to each other by means of sockets and set-screws and by attaching the lifting chain or chains to an up curving shoe turning freely on thejackscrew, all as hereinafter described.

In the accompanying drawings, wherein like letters represent like parts, Figure 1 is a general perspective view of the machine, and Fig. 2 a sectional view thereof takenlongitudinally through the centers ofthe feet, standards, cross-head, and jack-screw.

A A are standards (preferably tubular) litting at one and either end into the annular sockets b b upon the feet B B, and tightened therein by the set-screws b b', and tting at the other and either end into the annular sockets c c, formed in the cross-head C, and tightened therein by set-screws c c. The feet B B have corrugated soles b2 b2, to give them a firmer hold upon their supports when the machine is in operation.

Thejack-screw D works in a threaded socket, c2, formed in the cross-head C. Its head is provided with sockets d d for the insertion of lever-bars to operate the machine. At the lower end a spindle, d', is formed, upon which turns a shoe, E, said shoe having an orifice, e, for the insert-ion of the spindle. The shoe is detachably kept in place by means of anut, d2, screwing upon the spindle, or by any other suitable andfamiliar means. The pivot arrangement of the shoe enables it to be set at any plane angle toward the rail or stringer to be lifted.

Chains F F, provided with rings ff and hooksff, t upon the toes of the shoeE, and are passed under the rail or stringer, as the case may be, it being in contemplation to use but one chain in ordinary track-lifting.

I am aware that track-raisers and other similar machines are now operated by means of a jackscrew set vertically; hence I do not claim such a device, broadly; but

I claim as follows:

The combination, in a track-raiser, of standards A, with the feet B, having sockets b, setscrews b', and corrugated soles b2, the crosshead C, having sockets c, set-screws c', and screw-socket c, the jack-screw D, having lever-holes d and spindle d', the shoe E, with orifice e, and the chains F, with rings f and hooksf, in the manner and for the purposes described.

In testimony whereof I aflx my signature in presence of two witnesses.

JACOB B. LATSCHAW.
